Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of U.S.
Provisional Application No. 62/314,989, filed Mar. 29, 2016,
entitled "SYSTEM AND METHOD FOR PEEP HOLE SECURITY", which is
hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] The present invention generally relates to a peep holes.
More particularly, the present invention relates to security
systems and methods for peep holes.
[0003] Current peep hole designs suffer from several drawbacks that
may be exploited by the unscrupulous to obtain undesired optical
intrusion into the interior of a room. For example, current peep
hole bezels may typically be rotated from the exterior surface of
the door. Unfortunately, when rotated, most peep holes may be
removed from the door, which may allow an undesired party to see
into the room.
[0004] Alternatively, optical devices exist that may be positioned
over the bezel at the exterior of the peep hole, but will provide
the unscrupulous user with an optically modified image so that the
user may clearly see the interior of the room. In order to combat
this, responsible hotels may install internal peep hole covers that
optically block the peep hole. Unfortunately, such peep hole covers
are typically attached to or responsive to the internal surface of
the peep hole. Consequently, rotation and/or jiggling of the peep
hole may cause the peep hole cover to become dislodged, which may
then allow unscrupulous user to use an optical device to see into
the room.
BRIEF SUMMARY OF THE INVENTION
[0005] One or more of the embodiments of the present invention
provide peep hole security systems and methods. In one embodiment,
a peep hole security system includes a threaded optical shaft
including a cylindrical central shaft having an exterior thread and
a bezel having an optical element. The bezel has an interior bezel
surface with a security pin. The cylindrical central shaft and
security pin are introduced into holes in the exterior portion of a
door. A threaded interlocking cylinder including an interior thread
and an interior flange is then provided. The interior thread of the
threaded interlocking cylinder is then rotationally threaded into
the exterior thread of the threaded optical shaft until the
interior bezel surface is brought into contact with the exterior
surface of the door and the interior flange is brought into contact
with the interior surface of the door. Rotation of the threaded
optical shaft is therefore prevented because attempts to rotate the
threaded optical shaft cause the security pin to contact the
interior of its hole and prevent rotation of the threaded optical
shaft.

DETAILED DESCRIPTION OF THE INVENTION
[0013] FIG. 1 illustrates a peep hole security system 100 according
to an embodiment of the present invention. The peep hole security
system 100 includes a threaded optical shaft 130 and a threaded
interlocking cylinder 150. The threaded optical shaft 130 includes
a bezel 110 having a flange 120 and an interior bezel surface 122,
a security pin 140 having an exterior security pin surface 142, and
an exterior thread 132 positioned on the central shaft of the
threaded optical shaft. The threaded interlocking cylinder 150
includes an interior thread (not shown) and interior flange 155
having an interior flange surface 157. As shown in FIG. 1, the
exterior thread 132 of the threaded optical shaft 130 has been
partially threaded into the interior thread of the threaded
interlocking cylinder 150 as further described below.
[0014] Additionally, the threaded optical shaft 130 and threaded
interlocking cylinder 150 are generally cylindrical in shape and
when threaded together form an optical pathway from an optical
element (not shown) positioned at the exterior surface of the bezel
110 through the threaded optical shaft 130 and threaded
interlocking cylinder 150 to an internal viewing aperture (not
shown) formed by the interior flange 155.
[0015] Additionally, as shown in FIG. 1, the security pin 140
extends from the interior bezel surface 122 in the direction of the
cylindrical central shaft of the threaded optical shaft 130. In one
embodiment, the security pin 140 may be parallel to the cylindrical
central shaft.
[0016] In operation, when the peep hole security system 100 is
installed into a door, a main hole is drilled in through a door to
accommodate the optical shaft 130. This hole may be referred to as
the optical shaft hole. Further an additional, smaller drill hole
that conforms to the size of the security pin 140 is drilled into
the exterior surface of the door to accommodate the security pin
140. The optical shaft 130 is then introduced into the optical
shaft hole in the door and the security pin 140 is introduced into
the smaller drill hole, which may be called the security pin hole.
The optical shaft 130 and security pin 140 are induced into their
respective holes until the interior bezel surface 122 of the bezel
110 comes into contact with the outer surface of the door.
[0017] Once the optical shaft 130 and the security pin 140 are
installed into their respective holes, rotational movement of the
peep hole security system is constrained. More specifically, if a
person attempts to rotate the bezel 110, the exterior security pin
surface 142 is quickly brought into contact with the interior
surface of the security pin hole and rotational motion of the bezel
110 is prevented.
[0018] To complete the installation of the peep hole security
system 100 in the door, the interior thread of the threaded
interlocking cylinder 150 is then rotationally threaded onto the
exterior thread 132 of the threaded optical shaft 130 until the
interior flange surface 157 of the interior flange 155 comes into
contact with the interior surface of the door. Once the interior
flange surface 157 of the interior flange 155 comes into contact
with the interior surface of the door and the interior bezel
surface 122 of the bezel 110 is in contact with the outer surface
of the door, further rotational threading is prevented, thus
restraining further tightening.
[0019] FIG. 2 illustrates a perspective view 200 from the interior
side of the threaded optical shaft 130. FIG. 2 also shows the bezel
110, flange 120, interior bezel surface 122, security pin 140,
exterior security pin surface 142, and exterior thread 132. As
discussed above, in operation the exterior thread 132 of the
threaded optical shaft 130 is threaded into the interior thread of
the threaded interlocking cylinder 150. Light passes through the
threaded optical shaft 130 from an optical element (as shown in
FIG. 4) positioned in the exterior surface of the bezel 110 and
exits the threaded optical shaft 130 at the threaded optical shaft
optical pathway exit aperture 134.
[0020] FIG. 3 illustrates a perspective view 300 of the interior
side of the threaded interlocking cylinder 150. FIG. 3 shows the
interior flange 155 and interior flange surface 157. Additionally,
FIG. 3 shows the interior thread 159 of the threaded interlocking
cylinder.
[0021] Also, as discussed above, in operation the exterior thread
132 of the threaded optical shaft 130 is threaded into the interior
thread of the threaded interlocking cylinder 150. Light passes
through the threaded optical shaft 130 from an optical element (as
shown in FIG. 4) positioned in the exterior surface of the bezel
110 and exits the threaded optical shaft 130 at the threaded
optical shaft optical pathway exit aperture 134 and then in turn
enters the threaded interlocking cylinder optical pathway entrance
aperture 158 of the threaded interlocking cylinder 150. The light
then passes though the threaded interlocking cylinder 150 to an
internal viewing aperture (not shown) formed by the interior
surface of the interior flange 155.
[0022] FIG. 4 illustrates a perspective view 400 from the exterior
side of the threaded optical shaft 130. FIG. 4 also shows the bezel
110, flange 120, security pin 140, exterior security pin surface
142, and exterior thread 132. Additionally, FIG. 4 shows the
optical element 160 positioned at the exterior surface of the
optical pathway through the peep hole security system 100.
[0023] FIG. 5 illustrates the threaded optical shaft 130 of the
peep hole security system 100 during installation into a door 105.
As shown in FIG. 5, the door 105 includes an optical shaft hole
109, outer door surface 108, and a security pin hole 107.
Additionally, the optical element 160, bezel, 110, flange 120,
exterior thread 132, security pin 140, and exterior security pin
surface 142 are also shown.
[0024] As shown in FIG. 5, the threaded optical shaft 130 as been
introduced into the optical shaft hole 109 and the security pin 140
is being introduced into the security pin hole 107. Next, the
threaded optical shaft 130 and security pin 140 are further engaged
with their respective holes 109, 107 until the interior bezel
surface 122 (not shown) comes into contact with the outer door
surface 180 of the door 105.
[0025] As discussed above, to complete installation of the peep
hole security system, the interior thread 159 of the threaded
interlocking cylinder 150 is threaded into the exterior thread 132
of the threaded optical shaft 130 and rotationally threaded until
the interior flange 155 of the interlocking cylinder 150 is brought
into contact with the interior surface of the door 105.
[0026] In one embodiment, when installed, the interior bezel
surface 122, may be in contact with, abutting, and/or positioned
proximal to the outer door surface 108. Similarly, in one
embodiment, when installed, the interior flange surface 157 may be
in contact with, abutting, and/or positioned proximal to the inner
door surface.
[0027] In one embodiment, the security pin hole 107 only extends
into the exterior surface of the door a sufficient distance to
accommodate the height of the security pin. In another embodiment,
the security pin hole 107 may extend through the door.
[0028] In the embodiment shown in the figures above, the security
pin 140 was circular in cross-section. However, in other
embodiments, the security pin may be square, triangular, or
hexagonal or octagonal.
[0029] One additional feature of the peep hole security system 100
is that it is tamper evident. For example, in some cases,
pranksters or malicious persons who have access to the interior of
a hotel room may unscrew and/or remove a peep hole from the inside
of the hotel room and then re-install the peep hole backwards.
Unless corrected or otherwise blocked, the peep hole may then allow
someone outside the door to directly look into the interior of the
hotel room without even requiring the assistance of an optical
device.
[0030] However, with peep hole security system 100 shown in FIG. 1,
even if a malicious person inside a hotel room removes the peep
hole and attempts to re-install the peep hold backwards, the
security pin 140 will come into contact with the interior surface
of the door (there is no security pin hole on the interior surface
of the door for the security pin to enter) and prevent the interior
bezel surface 122 from coming into contact with the interior
surface of the door. Thus, the bezel 110 will protrude from the
interior surface of the door by a distance equal to the height of
the security pin 140.
[0031] The protrusion of the bezel 110 thus serves as tamper
evidence that is readily recognizable by a subsequent user of the
hotel. The protruding bezel 110 looks very strange and is
immediately recognized by users that something is wrong with the
peephole.
[0032] One advantage provided by the present peep hole security
system 100 is that because the security pin 140 engages with the
exterior surface of the door, if a person outside the door attempts
to rotate the bezel 110, the edges of the security pin 140 will
engage with the surface and/or interior of the door and prevent the
bezel 110 from being rotated, thus locking the bezel in place.
[0033] This represents a considerable improvement in current peep
hole technology because current peep hole bezels may typically be
rotated from the exterior surface of the door. Unfortunately, when
rotated, most peep holes may either be removed from the door, which
may allow an adverse party to see into the room, or the rotation of
the bezel may cause an internal peep hole cover to be dislodged,
which may allow an adverse party having certain optical devices to
see into the interior of the room. Fortunately, the present peep
hole security system 100 can counteract this security flaw by
preventing the rotation of the bezel from outside the room.
[0034] In one embodiment, the pin or other part of the design may
be tapped and/or bonded, for example, by being of tempered alloy,
it may allow the economy of casting, while achieving much of the
strength of a forged and tempered steel, which is an alternative
design. Additionally, one or more components of the design may be
made of plastic or other rigid material.
[0035] In one embodiment, the pin may be welded or brazed.
Alternatively, one or more portions of the design may be casted or
machined. In one example, one or more portions of the design may be
machined from a forged billet.
[0036] In one embodiment, a tapped and/or threaded hole is placed
on the back of the peephole bezel, and with a hole bored through
the door to meet it, a bolt threaded through the door from the
inside and tightened into the tapped and threaded hole located on
the back of the peephole's exterior bezel.
[0037] In one embodiment, a greater number of pins, such as two,
three, or four pins may be used in place of the single pin.
[0038] In one embodiment, the interlocking peephole and door
relationship allows them to be mated/nested from one side and
remain free of manipulation/rotation from one side after
installation. Though still removable when required, provided there
is access from the authorized side.
[0039] In one embodiment, for the threading of nut, or sleeve or
bolt from a single opposite planar side--where it may then still be
tightened with the desired threaded sleeve, or nut--with no further
application of mechanical force being needed on the interlocking
flange side of the door. A one person install, or easier install
with less time and effort needed to isolate the other side with
application of an opposing mechanical force.
[0040] Thus, in one embodiment, because the pin prevents the
rotation of the peep hole once it has been introduced into the
door, it becomes easier to thread the locking sleeve onto the
exterior of the optical shaft from the inside of the door because
it is no longer necessary to simultaneously hold the exterior bezel
while threading the locking sleeve. Consequently, it may be easy to
install, installation may proceed faster, installation may require
fewer hands, and/or installation may require fewer resources.
[0041] And with less application of force less than what would
effectively break the components--being in any way practical to
apply--the present design provides a security feature.
Additionally, one or more embodiments may provide isolation from
vibration, movement, and human tampering from that side as well as
easier maintenance, as only a single side must be checked or
retorqued.
[0042] Additionally one or more embodiments may provide a secure
feature that unlike welding, is not material substrate and alloy
compatibility dependent, nor is it destructive or overly
intensive/invasive for authorized installation/maintenance removal
upgrade and is not destructive or difficult to perform the same,
compared to an adhesive/epoxy and boasts better mechanical
advantage/strength.
[0043] Also, one or more embodiments may provide an aesthetic
benefit including stealth/clean assembly with hidden fasteners.
Also, only the opposite side remains free to turn, to either
tighten or loosen the assembly. As the peephole's bezel completely
hides the fasteners in the flange which isolate the flange from
movement. This solves concerns of tampering from the unsecure side
of the component (door). As with the compressive force of the
assembly tightly mating the (door) and component with an
interlocking bias coordinate that is separate and distinct in
location--additional to the equidistant coordinate of the shared
threaded shaft which interlocks with the door. Further, one
embodiment may be used in metal applications--including
applications other than doors.
[0044] In one embodiment there is an alternative to welding for
there to be reduced input heat into the assembly or part--and
reduction of the HAZ that is of concern with weakening and warping
metals or removing tempering (T6-6061 AL for example) or the 2000
series of AL alloys in aeronautics that are notoriously problematic
for welding.
[0045] One embodiment provides an alternative to traditional bolt
and nut assembly: easier installation and security from tampering
or vibration.
[0046] One or more embodiments may provide one or more of the
following advantages.
[0047] One or more embodiments may allow design of a tight/limited
space assembly. Where a design has to address or imposes space
restraints in a mechanical assembly--where it might only allow a
tool wielding operator to access one side but not the other.
[0048] One or more embodiments may be used where currently they
might otherwise currently rely upon a costly manufacturing
application of a threaded tap to machine a thread into the part, so
it allows access from one side to torque and thereby eliminating
requirement for access to the other side of the component during
assembly and repair:
[0049] One or more embodiments may be improved upon by more
strength with bolt through diffusion of mechanical force
applied/required to endure--instead of reliance upon the narrower
diffusion of force in a partially tapped assembly.
[0050] One or more embodiments may be provided at less
manufacturing cost, being only 2 holes instead of tapped and
machined threads, and a mass produced part inserted likely held in
place during assembly with a light duty/temporary adhesive.
[0051] One or more embodiments may resist galvanic corrosion: for
example where currently there is often an instance of a steel bolt
being threaded into a tapped and threaded hole in an aluminum pump
or engine block--the threads seize, corrode from galvanic corrosion
of dissimilar alloys, then bolts break off--requiring expensive
specialty boring and retapping and alternate bolts be made for
appropriate application--increasing downtime, and maintenance
costs.
[0052] One or more embodiments may avoid the aluminum threads which
are also much weaker than steel, and there are creep factors with
thermal cycling, particularly in dissimilar materials that as weak
points downgrade the effective longevity and capacities of a system
to elements and time, heat soak, stress hardening, and shock.
[0053] One or more embodiments may provide a one piece iteration of
this insert and collar with pin (like the peephole side with its
pin) may be formed around a steel barrel with internal threads and
efficiently mass produced in varying sizes--like most fasteners are
and, like nuts and bolts, may be mass produced.
[0054] One or more embodiments may have Carbon fiber translating
mechanical force between dissimilar alloys, with the above
mentioned bolt through advantage of greater footprint diffusing
force over more material--while acting as an intermediary between
direct contact, like a galvanic coupling, keeping the contact
between Steel and Aluminum separate.
[0055] One or more embodiments may allow the continued application
of Steel to Steel threading for mechanical strength and thereby
raising the effective temperature ranges, and retained compressive
strengths at those thresholds the bonded assembly has against creep
and catastrophic failure. This may be done elsewhere to for caustic
service resistance, for example, by allowing more flexibility in
materials chosen.
[0056] One or more embodiments may be used at higher pressures,
higher temperature ranges, and provide higher longevity.
[0057] For one or more embodiments, when the system fails, the same
bolt, and size may be used. In this case, the old one is pushed out
of the holes, and a new assembly is put in its place, so less
maintenance, and when and if required, easier and cheaper to deal
with than a snapped bolt in a tapped and threaded hole.
[0058] One or more embodiments lowers lifetime cost of maintenance
and reduced downtime, while allowing more robust engineering and
capabilities in machines.
[0059] One or more embodiments provides an interlocking
flange/backplate/security collar screwed to door.
[0060] In other embodiments, a circular (shape is aesthetically
preferred for reduced door footprint, but the bezel and/or flange
may be of any shape, such as ovoid, square, rectilinear, or
trapezoidal. Economics of manufacturing also prefer less mass, but
not exclusive to working to provide the security/one way aspect of
bolt mechanism) flange that is the same or only slightly larger
diameter than the back of the peephole.
[0061] In one or more embodiments, the flange is recessed with a
recessed embossing or negative imprint and the peephole back is the
positive nested coordinates. Or the inverse--so long as the two
components are Interlocking. Which can be a 3d cavity of any 2d
shape whose entirety of planar points are not equidistant to a
single point, such as a star of any point, an oval, square, any
matter of polygon etc. It is also acknowledged that while a circle
can circumscribe any shape--the shape which it circumscribes--no
matter how affinitive, is not comprised exclusively of planer
points that are not equidistant. Additionally, shapes other than a
circle, such as a triangle or polygon or star or square may be
employed. Additionally, several circles or shapes that are recessed
into the flange may also be employed.
[0062] One or more embodiments the flange has a hole in the center
to allow a peephole tube to pass through, and two or more
countersunk holes that allow screws or bolts (threaded fasteners)
of matching shoulder pitch to secure to surface on which it is
installed, while remaining flush, or lower than the flange's
highest point or maximum standoff. The peephole is then placed
through the hole of the flange and the component (door for this
iteration) that the flange has been installed on. The interlocking
surfaces are mated/nested and then the other side can be tightened
with the desired threaded sleeve, or nut--with no further
application of mechanical force being needed on the interlocking
flange side of the door to prevent rotation due to the engagement
of the pin with the door. And with no application of force less
than what would effectively break the component being practical to
apply, which is a security feature. Further, the embodiment
provides isolation from vibration, movement, and human tampering
from that side, as well as an aesthetic benefit such as a
stealth/clean assembly with hidden fasteners. Only the opposite
side remains free to turn, to either tighten or loosen the
assembly. As the peephole's bezel completely hides the fasteners in
the flange which isolate the flange from movement.
[0063] Assuming the planar surface of install was vertical, such as
a door (y axis), (whose thickness would then be x-axis) the
assembly may first be removed from the opposite side of Door Y, to
reduce the compressive force mating the interlocking assemblies,
until at least which time as there is enough play/or movement of
threaded shaft's length (x-axis), of the bolted assembly to allow
the assemblies to be separated off/out of one another--which only
then assembly be turned manipulated/unthreaded from the flange
side.
[0064] One or more embodiments the flange may be bonded with fusion
or welding or adhesives or compressed depending on the
compatibility and end use of the materials to allow mass assembly
without the cost of holes and screws.
[0065] One or more embodiments allow a simple install; without need
of jig or measuring to place bore hole for pin. As the flange
places the pins (screws or bolts, even nails) in the correct
location. Additionally, one or more embodiments may use a cast
assembly for peephole, and a stamped or formed, possibly even
machined flange, or both components being cast may be cheaper than
bonding a tempered pin into a part.
[0066] FIG. 6 illustrates an alternative embodiment of a bolt
security system 600 including a security bolt 630 having a security
pin 640. The bolt 630 includes a bolt head 610, an interior bolt
head surface 622, a central shaft threaded portion 632 and a
central shaft non-threaded portion 634. The security pin 640 has an
exterior security pin surface 642.
[0067] In operation, the bolt security system 600 performs
similarly to the peep hole security system 100 described above. For
example, the bolt 630 may be positioned in a bolt hole extending
through a surface and the security pin may be introduced into a
pre-formed security pin hole in the exterior side of the surface.
The bolt may then be tightened to the exterior side of the surface
by rotationally threading a standard nut onto the central shaft
threaded portion 632, much like the threaded interlocking cylinder
150 threads into the threaded optical shaft 130 of the peep hole
security system 100. Tightening the nut brings the nut into contact
with an interior side of the surface through which the bolt extends
while also bringing the interior bolt head surface 622 into contact
with the exterior side of the surface.
[0068] Additionally, as described above with regard to the peep
hole security system 100, once the security pin is placed in the
security pin hole in the exterior side of the surface and the nut
is tightened, the bolt head 610 is not rotatable from the exterior
side (bolt head side) of the surface. Attempts to rotate the bolt
head 610 cause the exterior security pin surface 642 to contact the
side of the security pin hole and prevents rotation.
[0069] FIG. 7 illustrates an alternative embodiment of a nut
security system 700 including a security nut 730 having a security
pin 740. The nut 730 has an interior nut head surface 722 and a nut
threaded portion 750. The security pin 740 has an exterior security
pin surface 742.
[0070] In operation, the nut security system 700 performs similarly
to the peep hole security system 100 and bolt security system 600
described above. For example, a standard bolt may positioned in a
bolt hole extending through a surface with the head of the bolt on
an interior side (secure side) of the surface, which allows a nut
to be threaded onto a threaded portion of the bolt that extents to
an exterior side (unsecure or public side) of the surface.
Additionally, on the exterior side of the surface a pre-formed
security pin hole may be established.
[0071] The security pin 740 of the security nut 730 may be
introduced into the security pin hole and then a standard bolt may
be passed through a bolt hole in the surface so that the threaded
portion of the bolt rotationally engages the threaded nut portion
750. Tightening the bolt brings the head of the bolt into contact
with an interior side of the surface through which the bolt extends
while also bringing the interior nut head surface 722 into contact
with the exterior side of the surface.
[0072] Additionally, as described above with regard to the peep
hole security system 100 and bolt security system 600, once the nut
security pin is placed in the security pin hole in the surface and
the bolt is tightened, the security nut 730 is not rotatable from
the exterior side (nut side) of the surface. Attempts to rotate the
security nut 730 cause the exterior security pin surface 742 to
contact the side of the security pin hole and prevents
rotation.
[0073] Both the security nut and security bolt embodiments include
the addition of a security pin that may be introduced into a
pre-formed hole in the surface to which the nut or bolt will abut
in operation, much as described above with regard to the peep hole
security system. This embodiment may represent an improvement on
the lock washer so that a lock washer may no longer be needed. More
specifically, a higher degree of isolation from rotation provided
by fixing one set of threads with a locking pin into a component
side in that the threads do not turn without the component they're
pinned into being rotated. For example, the peephole's exterior
fastener does not rotate once pinned into the door.
[0074] Additionally, other embodiments may be employed in
applications where the lock washer may not be dependable enough to
lock the thread's ability to rotate without the component they are
mounted in rotating. For example, the threads being in an engine
block prevents it from coming loose unless the bolt is reversed out
with a tool, and a user need not hold a wrench on the other side to
tighten or loosen a connection.
[0075] In one embodiment, static threads that are fixed in their
orientation with the component may be pushed or inserted into
place, allowing the use of different materials for the thread
assembly than necessarily what the component's parent material is
and may also provide the ability to replace the threading if they
break.
[0076] For example, if a user were removing a valve cover on an
operational engine or a turbine housing that is in the field, and
installed and a bolt broke off, the user would have to pull the
entire assembly and re-tap and thread for a larger bolt, or to
maneuver a tapping die into confined space, often at awkward
angles, and tap new threads. The other alternative is to have back
up components with all their costly manufactured threads and
machining on hand to replace it completely and scrap the old piece
that is compromised now, with threads stripped, or bolts broken off
inside threads.
[0077] However, if the threads were a female threaded tube, (or
male threaded stud) with locking head or collar placed in a smooth
bore hole--then damaged threads would only be a matter of pushing
out the old thread assembly, and inserting a new (pre manufactured
one) of the appropriate size. (Initial Machining of threads could
also be done at a higher throughput rate, like a screw machine
instead of a multi axis CNC (computer numerical control) having to
reach around a component and position itself for each angle and tap
cut threads into it.) Then it could be bolted back together.
[0078] In an engine or other automotive component, for example,
many bolts or threaded bolt receiving ports may be employed and may
be integral to the structure in which they are found. All of those
bolts go into the assembly which is tapped, and if any one of those
failure points fail: the entire component needs to be re machined
to possibly salvage or scraped and replaced. Many times these large
components are made of aluminum alloys to reduce weight, yet the
bolts are steel. This reduces the pressure the threads can hold and
the inability to keep all threaded components of steel, means this
will suffer galvanic corrosion and ultimately fail.
[0079] Thus, in one embodiment, instead of needing to re-machine
threads into components that had their threads cut directly into
the substrate of the component at time of manufacture, the user may
simply acquire and use another from a bin of interchangeable items,
such as nuts are employed today. In this embodiment, the threads
are already there, and the user does not have to machine any
assemblies during the repair to complete it. Using standard
interchangeable threads, instead of threads that are bored into,
and machined out of the parent assembly. Thus the prior art is not
fault-tolerant: a stripped thread, or frozen thread that breaks
off, bent threads, rusted or oxidized threads, even at time of
manufacture, and error in the casting or in the threading that does
not achieve good threads requires the entire costly assembly needs
machining repair or is wholly lost, and needs replacement.
Conversely, in the new embodiment, if it's just a small
interchangeable part that new insert may be placed and the
component not only readily returned to original specs, but the
damage may be isolated to a small part instead of the entire
component.
[0080] Further problems with the prior art that increase the
desirability of the present embodiment include the fact that prior
art structures include studs such as those used in a turbine, that
may be integral to the structure itself and extend outwardly from
the structure. Such systems may still benefit from one or more of
the present embodiments by not requiring access with a tool to the
opposite side of the flange, for example, to keep the threads from
rotating while tightening the nut, as described above with regard
to the threaded stud like the peephole assembly, and passed through
a hole in the flange, and the head had a pin locking into the
flange. In this embodiment, if a stud is broken, the user may just
hammer out the old one and insert a new one without the need for
rethreading.
[0081] While particular elements, embodiments, and applications of
the present invention have been shown and described, it is
understood that the invention is not limited thereto because
modifications may be made by those skilled in the art, particularly
in light of the foregoing teaching. It is therefore contemplated by
the appended claims to cover such modifications and incorporate
those features which come within the spirit and scope of the
invention.
